WATER-CLOSET VALVE.

SPECIFICATION forming part of Lettrs Patent No. 310,972, dated January 20, 1885.

Application filed March 28, 1884. No model.)

To (LZZ whom, it may concern:

Be it known that I, HERMANN G. APEL, of Milwaukee, in the county of Milwaukee and State of \Visconsin, have invented a new and Improved Water-Closet Valve, of which the followingis a full, clear, and exact description;

The object of my inventionis to provide a new and improved watercloset valve, which is not provided with any springs, and is closed automatically by the pressure of the water.

The invention consists in the combination, with a water-closet bowl or other vessel,of an inlet-pipe, forming a cylinder or casing, from which a pipe extends to the bowl, in which casing a cylinder is formed,containinga piston or plunger having a stem, which plunger can be raised and pressed up by water admitted into the bottom of the inner cylinder against a neck on the bottom of the lower end of the pipe extending from the above mentioned casing or cylinder to the bowl, thus shutting off the water from the bowl.

Reference is to be had to theaecompanying drawing, forming part of this specification, in which alongitudinal sectional elevation of a water-closet provided with my improved water-closet valve is shown.

A represents the earthenware bowl, which is suitably supported; B, the hopper, having an overflow, O; D, the outlet-pipe of the hopper; E, a brass ring or valve-seat in the top of the said opening, and F a valve for closing the said opening. The water-inlet pipe G terminates in a cylinder or casing, H, in which a smaller cylinder, J, is held concentrically, and thus forms an annular water-chamber, K, which is in communication with the inlet-pipe G.

From the bottom of the cylinder J apassage, L, extends into the inlet-pipe G, and is provided at its free end with a valve or gate, G, connected with a screw, G projecting down through the top of the inlet-pipe G. Aeurved or other pipe, M, extends from the top of the bowl A to the casing or cylinder H, and is provided on the bottom of its lower outer end with a short downwardly-projecting neck, N, which has a smaller diameter than the cylinder J and the free lower edge of which neck N is a short distance above the top of the cylinder J. A piston or plunger, 0, fitting closely in the cylinder J, is secured to the lower end of a vertical stem, I, which passes loosely through a plunger, 1?, and into the lower end of a hollow stem, S, to the lower end of which the plunger P is fastened, which stem passes through a packing, Q, and through the top cap, It, of the cylinder H. An upwardlyprojecting lever, T, is pivoted to a bar, T, to swing in a vertical plane, and to its lowerend a connecting-rod, U, is pivoted, which is also pivoted to the valve F. A beveled prong, V, projecting laterally from the lever T, rests on the top of the stem S.

The operation is as follows: When the valve is closed, the top of the piston O rests against the bottom edge of the neck N and closes the same, thus preventing the water from passing into the bowl A. The lever T is swung in the direction of the arrow a. Thelower end of the said lever T withdraws the valve F, thus permitting the water in the bowl and hopper to flow ofl' into the waste-pipe. At the same time the prong V presses the stem S and the plunger P downward and the stem S presses the piston 0 down, thus permitting the water to flow from the pipe G through the annular space K between the top of the cylinder J and the neck N over the top of the piston O and through the pipe M into the bowl. If the pressure is removed from the lever T, the wa ter entering the bottom of the cylinder J through the pipe or inlet L forces the piston O upward and against the edge of the neck N, and also raises the plunger 1?, and thus the water is cut oii'. The plunger P prevents all waste of water. The quantity of water admitted into the closet B is regulated by the valve G.

The abovedescribed valve can also be used on hopper-closets and for other like purposes.

I am aware that, broadly, it is not new to employa valve or piston fixedly connected to a controlling-valve; nor to eiiect the automatic closing of the valve by the action or pressure of the water.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a piston working in acylinder and forming the valve, of a lever for pressing down the piston, and of an cylinder H with the bowl, and havinga downwardly-projecting neck, N, above the piston 0, said stem extending loosely into the tubular stein S of the plunger R, substantially as herein shown and described.

3. The combination, with the bowl A or other vessel, of the inlet-pipe G, the cylinder or casing H, the pipe M, connecting the cylinder or casing H with the bowl, and having a downwardly-projecting neck, J, the piston 0, working in the cylinder J, and having an upwardly-projecting stem, said neck or valveseat N being slightly elevated above the cylinder J, and said cylinder J, together with the casin g H, forming the water-chamber from which the water enters said neck or seat, the

inlet-pipe L at the bottom of the cylinder J,

the screw G", and the valve G, substantially as herein shown and described.

4. The combination, with the bowl A, ofthe water-inlet pipe G, the pipe llLconnecting the pipe G with the bowl, the cylinder J, the inlet-pipe L in the bottom of the same, the piston O, the stem 1, the plunger P, the hollow stem S, the lever T, the projection on the lever T, the valve F, and the rod U, connecting the lever T with the valve F, substantially as herein shown and described.
